More and more customers have become worried about the environment, so many companies have begun working to develop paper bottles. Paper bottles have many advantages. Perhaps the most important is that they can be easily recycled. Paper bottles also weigh less than glass or plastic ones and they’ll require less energy to produce and to move around. Since paper is soft and easy to be shaped, companies can design their bottles to take almost any shape they choose.

A company called Paboco has been working with many large companies to develop paper bottles. The companies are creating their own bottle designs, but they’re sharing what they learn to speed up the development of paper bottle technology.

Clearly, one of the biggest challenges is keeping a paper bottle from leaking (漏). Many companies are lining (做内衬) their bottles with a thin sheet of plastic. Though bottle makers may say they can be removed, many recycling programs don’t have the right machines to produce them.

A company named Diageo has just announced the first paper bottle that is completely plastic - free. Instead of a plastic liner, a non - plastic (无塑料) coating will be used on the inside of the bottles. This should make the bottle fully recyclable. But even without the plastic, paper bottles aren’t perfect, which means more trees need to be cut down to make the bottles.

There’re still lots of tests to be done before paper bottles can be used widely. But with so many companies working towards the same goal, it’s likely that we can expect to see paper bottles on store shelves in the near future.

Congratulations to the China National Space Administration on the launch of three “taikonauts” on their Shenzhou 12 mission to the Tianhe (Heavenly Harmony) space station.

On June 17th, 2021, in their Tweets to congratulate China on the launch of three “taikonauts” on their Shenzhou Ⅶ mission to outer space, both the European Space Agency and Roscosmos used the word “taikonauts”.

With the Greek word “naut”, which means sailor, and “taiko”, the Chinese word for space, the word “taikonaut” is specifically used for Chinese astronauts.

Yet “taikonauts” is more than just a word. Its history shows that of China’s space journey. Started in 1992, the manned spacecraft engineering (载人航天工程) of China was far behind the USA and Russia in the beginning 6 years later, a Chinese Malaysian, who used it first in newsgroups. However, back then few people picked up on it, as China was still rather weak at that time.

It was not until 2003, when China sent Yang Liwei, the first taikonaut into space taking the Shenzhou Ⅴ that the word became widely known. In his speech at Peking University on Friday, Yang told stories about that and shared how much is required of the taikonauts to prepare them for their missions.

Since 1998, China has 34 trained taikonauts, each of whom has passed tests that are usually unimaginably difficult. According to reports, engineers and scientists, and must pass a lot of test before becoming a real taikonaut.

Behind these taikonauts are hundreds of thousands of other workers that do their jobs to get the taikonauts into space and make certain of their safe return. It is the great efforts of everyone in this project that has made “taikonauts” from just a word on the paper into the reality, and all of them should share the honor of the taikonauts’ tasks. The meanings of the word will he further developed and we hope more taikonauts will appear.

【推荐1】Octopuses（章鱼）are kind of like aliens. They are amazing in many ways. They have three hearts. They can walk. They can swim, and they can drive themselves forward at high speed. They can change colour and copy what other animals do. They even know how to open screw-top jars（带螺旋盖的罐子）and how to use tools!

Octopuses are mollusks（软体动物）. But unlike many other mollusks, they don’t have a shell. This allows them to pass through tiny spaces. Although octopuses mainly eat small fish, they are able to attack and kill small sharks. They make the sharks unable to breathe by covering their gill（锡）openings.

One thing that makes octopuses seem like aliens is their blue blood. It is much better at transporting oxygen in cold and low-oxygen conditions(like the deep sea) than our red blood. Octopuses lose energy easily. This may help explain their outstanding intelligence: They can’t chase after their prey（猎物）for a long time. They must use clever tricks.

As a hunter, an octopus brings prey under control through the use of a powerful poison（毒）. The smaller the octopus, the stronger the poison. The ten-centimeter-long blue-ringed octopus is so poisonous that it can easily kill a grown man. Octopuses themselves can be delicious prey to many different animals in the vast（辽阔的）ocean, but they are clever enough to know how to keep themselves safe many of the times. With their colour changing skin, octopuses can easily “hide” themselves or flash alarming colours to frighten their enemies away. If that doesn’t work, the octopus will release a cloud of dark ink and quickly escape.

Perhaps the most amazing part of an octopus is its arms. They can turn in any direction. The arms are too complex to be controlled from a central brain. Instead, they work almost independently. An octopus gives instructions and believes that they will be carried out. This means that the animal doesn’t have a very good idea of where its arms are. They can’t work out the shape of something by feeling it like we can.
